Your students will love learning how mass affects force in this activity from Learning With the Lays! They will use ramps, cars, and weights in this hands-on activity. They will also use their measuring skills to measure distance in centimeters. This lab uses the scientific method and helps students create a question, state a hypothesis, perform an experiment, record results, and write a conclusion. The materials are easy to find and store in your classroom.
Fun With Mass is also in Fun With Force and Motion, available in my store. Fun With Force and Motion is a compilation of four lab activities: Fun With Force, Fun With Mass, Fun With Friction, and Fun With Inertia. It also uses the picture book, Sheep In a Jeep, to demonstrate science concepts. Best of all, it is 4 labs for the price of 3!
